hi everybody. i need a circuit which will short 2 cables for 0.5 seconds every second. let me explain like this:
_______________
(+2.4v) | | (0)
-----------| |--------------
| |
-----------------
in the ugly drawing above you can see two wires with a potential difference of 2.4 volts connected to a box. the box just represents the circuit that i want to make with your help.
this box must have zero resistance for 0.5 seconds and infinity resistance for 0.5 seconds. so its like a pulsating current with 1Hz across this two wires. Can you guys help me with this ? i have circuit elements like resistor, capacitor, leds, transistors(only BDX53C, BD243C, TIP41C and BDX54C), and etc... The timing doesn't have to be so strict, 0.5s+-0.05 is fine. The current that will be drawn during shorting is not high, not higher than 100ma. I need the simplest and most efficient circuit that you know :)
